Eddy, try looking at Macleaya. It usually does flower but yours may be
in the wrong conditions for that.

Good Morning, Sacha. Maybe mine HAS flowered but it seems the flower is
so unremarkable that I have not been impressed enough to remember it!

Here's some info I've just found on it:

"Plume Poppy (Macleaya cordata)

R.H.S. 'AGM' Award Winner

This is a splendid, impressive and statuesque plant that can grow to 8
ft. or more, with large, glaucous, finely sculptured leaves and very
large panicles, consisting of hundreds of tiny buff-coloured flowers,
carried well above the foliage. A bold, eye-catching plant. Hardy
throughout the British Isles. 8-12 ft."

And it's selling at about £5 a plant on the internet! They do look
rather fetching when massed together. But I guess many ugly things do!
